A novel versatile one-pot synthesis of 2H-4-chlorochromenes from 2′-hydroxychalcones have been developed. This method has been investigated for the synthesis of 2H-4-chlorochromen-2-ylpyrazoles.
Microwave-assisted synthesis of 1-{2-[(1-benzyl-1H-1,2,3-triazol-4-yl)methoxy]phenyl}-3-(3-aryl-1-phenyl-1H-pyrazol-4-yl)prop-2-en-1-ones and their antimicrobial activity

A series of new (E)-1-2-[(1-benzyl-1H-1,2,3-triazol-4-yl)methoxy]phenyl}-3-(3-aryl-1-phenyl-1H-pyrazol-4-yl)prop-2-en-1-ones (3a-3i) has been synthesized via copper-catalyzed 1,3-dipolar azide-alkyne cycloaddition reaction (CuAAC) of benzyl azide with substituted (E)-3-(3-aryl-1-phenyl-1H-pyrazol-4-yl)-1-[2-(prop-2-ynyloxy)phenyl]prop-2-en-1-ones (2a-2i). The synthesized compounds have been characterized by their IR, H-l, C-13 NMR spectra, and mass spectroscopy data. All the compounds have been screened for antimicrobial activity.
